In 24-h ambulatory blood pressure profiles there is overlap between the lowest systolic and the highest diastolic pressure in over 90% of the cases. An overlap is observed in about 75% of the cases when considering 90% ranges. The prominence of the 1.7-h ultradian component varies as a function of circadian stage and is found to be most prominent around mid-sleep.
在24小时动态血压曲线中,超过90%的病例最低收缩压与最高舒张压之间存在重叠。考虑90%范围时,约75%的病例中观察到重叠。1.7小时超日节律成分的突出程度随昼夜节律阶段而变化,发现在睡眠中期最为突出。
